Abstract
Manufacture of a 3D object by a printing method that enables the use of several reactive materials sequentially. A laser-enhanced jetting-based 3D printer forms successive layers of reactive compositions on one another and the first and subsequent layers are allowed to crosslink between the printings to ultimately form the 3D object. Additional reactive compositions may be printed prior to the crosslinking. The crosslinking may be effected by heating, with or without a catalyst, and post printing curing may be employed after the 3D object is formed.
Claims18
A method for fabricating a three-dimensional (3D) object, comprising:
- (a) printing a first reactive composition on a substrate with a laser-enhanced jetting-based 3D printer to form a first layer of the 3D object;
- (b) after formation of the first layer of the 3D object, jetting a second reactive composition towards the first reactive composition contained within the first layer with said laser-enhanced jetting-based 3D printer to form a mixture of the first reactive composition and the second reactive composition;
- (c) allowing the mixture of the first reactive composition and the second reactive composition to chemically react to form a compound;
- and
- (d) repeating steps (a) — (c) until the 3D object is formed.
